DS484Q/DS486Q Installation Instructions EN Quad Beam Photoelectric Detectors DS484Q/DS486Q | Installation Instructions | 1.0 Overview 1.0 Overview 1.1 Description The DS484Q and DS486Q are photoelectric quad beam detectors that use four pulsed infrared beams to activate an alarm relay upon detection of an intruder. Both models contain a transmitter that emits an invisible infrared beam, and a receiver. If the beam is broken, the receiver signals an alarm. Multiple channel operation provides increased system flexibility by allowing multiple devices to be used near each other without cross-talk or other interference. 1.2 Components Figure 1: DS484Q/DS486Q Components 1 2 3 10 11 5 6 4 12 13 7 14 15 8 16 17 9 123456- Chassis Base Cover Mounting holes Vertical adjustment screw (upper) Terminal block (transmitter has five terminals, receiver has nine terminals) 7 - Wire entrance 8 - Vertical adjustment screw (lower) 2 9 - Base mounting screws 10 - Optical module (upper) 11 - Scope (upper) 12 - Horizontal adjustment screw (upper) 13 - Operation panel (refer to Figure 2 or Figure 3) 14 - Optical module (lower) 15 - Scope (lower) 16 - Horizontal adjustment screw (lower) 17 –Cover mounting screw Bosch Security Systems, Inc. | 7/05 | 4998138530F DS484Q/DS486Q | Installation Instructions | 1.0 Overview .

Controlling beam intensity minimizes the risk of reflection off nearby walls and cross detection with other detectors. 1.3.3 Beam Interruption Time Control Use this feature to change the beam interruption time to best fit the application. 1.3.4 Using Multiple Transmitter-and-Receiver Sets Up to four transmitter-and-receiver sets can be stacked. 1.3.5 Selectable Beams The beams in the DS484Q and DS486Q are configurable into eight different combinations (two groups by four channels). These combinations can eliminate false alarms that can occur from cross-talk when multiple beams are stacked, or when the transmitter and receiver are separated by a long distance. The diameter of the transmitted beam increases with increased distance between the transmitter and receiver. At distances that approach the maximum range, the beam might reach two or more receivers. Refer to Section 2.1.2 Beam Spread on page 5 for additional information. Bosch Security Systems, Inc. | 7/05 | 4998138530F 3 DS484Q/DS486Q | Installation Instructions | 1.0 1.3.6 Selectable AND/OR Gate The photoelectric intrusion detection system in the DS484Q and DS486Q provides alarm relay activation for different considerations. Use the DIP Switches to select the required protection: AND gate – All four beams must be blocked simultaneously to cause an alarm. This setting results in fewer false alarms caused by birds and other small animals. OR gate – Either the upper or lower pairs of beams must be blocked. This setting can detect an intruder crawling on the ground. 1.3.7 Environmental Discrimination Circuit (EDC) The Environmental Discrimination Circuit (EDC) sends a signal when maintaining stable operation becomes difficult due to environmental disturbances. The EDC detects the gradual loss of signal along the beam’s path because of dirt built up on the cover, or because of rain, fog, or snow. If the signal decreases by 95% over at least 4-seconds, the EDC activates the EDC LED (refer to Figure 3 on page 3) and relay. This indicates that something is partially blocking a beam, or that the covers need cleaning. Overview Table 1: EDC BYPASS Switch States Detector Status BYPASS Switch OFF BYPASS Switch ON Poor Environmental Condition* EDC LED lights and EDC signal is provided through the normally-closed relay output at the receiver. EDC LED turns on and EDC signal is provided through the normally-closed relay output at the receiver. The alarm is generated by loss of beam energy. With the loss of beam energy, the ALARM LED lights but alarm signal is not generated (alarm relay is automatically shunted). EDC LED turns on and EDC signal is provided EDC LED turns on and EDC signal is provided. No alarm output is generated. If another optical module is blocked, the ALARM LED turns ON, but no alarm signal is generated. After the specified interruption time, the ALARM LED turns ON and alarm signal is generated. After the specified interruption time, the ALARM LED turns ON, and alarm signal is generated. If beams are blocked for more than 3 seconds, EDC LED turns ON, and EDC signal is generated. EDC LED does not turn ON, and EDC signal is not provided. When either optical module is blocked for 3 or more seconds. The EDC feature was not evaluated by Underwriters Laboratories (UL). Figure 4: Receiver DIP Switches When both optical modules are blocked for 3 seconds. 1 2 1 - DIP switches 1through 4 and 6 in the OFF position 2 - DIP Switch 5 (EDC BYPASS Switch) in the ON position To use the EDC Bypass Switch, set the receiver’s DIP Switch 5 to ON or OFF (Figure 4). Refer to Table 1 for information about the functions and detector status. ∗ Poor environmental condition refers to difficulty in maintaining stable operation due to environmental disturbances like fog or rain. Connect the EDC to a trouble circuit. Check the system after the EDC relay activates. 4 Bosch Security Systems, Inc. | 7/05 | 4998138530F DS484Q/DS486Q | Installation Instructions | 2.0 Installation . 2.1.1 2.0 Installation 2.1 Installation Considerations Read the following information before installing, wiring, and performing regular maintenance on the equipment. Do not install the detector: • near trees and plants where falling leaves can block the beam • where intense sources of light and sunlight can reflect directly into the receiver optics A beam of light shining at a ±3-degree angle of each receiver can cause false alarms. The beam strength is best if used within the maximum range of the detectors. If used for shorter distances, excess beam energy reaches the receiver resulting in reflection off nearby walls and incorrect communication with other detectors. 2.1.2 Figure 5: Beam Spread The beam spread is +0.7°. Refer to Figure 5 and Table 2 to determine the installation conditions. Table 2: Beam Spread Distances Between Transmitter and Receiver∗ m • • • • on movable surfaces where subject to splashing water or sea spray beyond the maximum range of each model where strong electrical noise or radio frequency interference occurs • where strong vibration occurs • in the presence of corrosive or explosive gas Face upper and lower optical modules toward each other on the transmitter and the receiver. • Do not install or wire detectors during a thunderstorm. • Do not supply power until all wiring is completed. • Maintain power between 10.5 VDC and 28 VDC at all times. • Do not disassemble or modify the base.

The first procedure (Section 4.2.2 Scope Alignment on page 14) is a visual alignment and is not precise. Use one of the additional procedures to complete the alignment. Table 9: Fine Alignment Considerations Alignment Procedure Considerations Voltmeter (Refer to Section 4.2.3 Voltmeter Alignment on page 15.) • Requires a voltmeter and a In the coarse alignment, if the installed devices do not face each other directly, the upper optical module and the lower optical module on each device are manually turned toward the opposite device. Then the opposite device is viewed through the scopes on the upper and lower optical modules while the horizontal and vertical angles are adjusted, using the turntable and the adjustment screws. Refer to Section 4.2.2 Scope Alignment on page 14. Fine Alignment The detectors have three possible fine alignment methods: Voltmeter, Level LED, and Sound. Alignment interruption sheets (Figure 19) are used in all three procedures to cover all optical modules in the installation except the pair that are being aligned. Select a procedure based on the conditions and considerations of the specific installation. Refer to Table 9. • Works well at any distance between the transmitter and receiver • Requires repeated observation of the voltmeter at the receiver Aligning a paired transmitter and receiver requires a coarse, or visual, alignment followed by a fine alignment. Coarse Alignment screwdriver Level LED (Refer to Section 4.2.4 Level LED Alignment on page 15.) • • • • Most accurate Might require two people Requires only a screwdriver More difficult to do when the transmitter and receiver are installed far apart • Requires repeated visual observation of the level meter on the receiver Sound (Refer to Section 4.2.5 Sound Alignment on page 15.) • Might require two people • Requires only a screwdriver • Works well at any distance between the transmitter and receiver • Does not require visual observation of the opposite device • Difficult to do in a noisy environment Figure 19: Alignment Interruption Sheet Bosch Security Systems, Inc. | 7/05 | 4998138530F 13 DS484Q/DS486Q | Installation Instructions | 4.0 Setup and Alignment 4.2.2 Scope Alignment 1.

When covering an optical module, align the punched holes in the interruption sheet with the scope apertures in the center of the optical module (Figure 21). Bosch Security Systems, Inc. | 7/05 | 4998138530F DS484Q/DS486Q | Installation Instructions | 4.0 Setup and Alignment . For synchronized applications or stacked sets of transmitters and receivers, install interruption sheets on all optical modules except the pair to be aligned. 10. Do one of the fine alignments. Refer to Table 9 on page 13 to determine which procedure to use. For the following procedures, make sure that all optical modules are covered with interruption sheets, except the pair to be aligned. Remove the interruption sheets and close the covers when the alignment is complete. 4.2.3 Voltmeter Alignment 1. Insert voltmeter leads into the alignment check terminals on the receiver panel. Refer to Figure 3 on page 3 2. Set the voltmeter scale to 10.0 VDC. 3. Use a screwdriver to adjust horizontal and vertical adjustment screws on the transmitter and the receiver. Refer to Figure 21 on page 14. 4. Check the voltage reading and continue to adjust the adjustment screws as necessary. In an ideal environment, the voltmeter value should be 3.0 VDC or higher. (The maximum voltage is 3.75 VDC.) 5. When the best voltage is achieved, the optical modules are aligned. 6. Repeat the procedure for the other optical module pair. 4.2.4 Level LED Alignment 1. Look at the Level Meter on the receiver. Refer to Figure 23. When you begin this procedure the LEDs are off. 2. Use a screwdriver to adjust the optical modules. Adjust the horizontal and vertical adjustment screws as necessary. Refer to Figure 21. 3. As more beam energy is received, each LED turns on, flashes quickly, flashes slowly, and then turns off. 4. Continue fine tuning until the LEDs turn off. • If outdoors, the alignment is complete when all LEDs are off. • If indoors, the alignment is complete when the lower two LEDs are off. 5. Repeat the procedure for the other optical module pair. Bosch Security Systems, Inc. | 7/05 | 4998138530F 4.2.5 Sound Alignment 1. Set DIP Switch 6 on the receiver to ON. Refer to Figure 23. 2. Use a screwdriver to adjust the optical modules. Adjust the horizontal and vertical adjustment screws as necessary. Refer to Figure 21. 3. As more beam energy is received, the sound pitch changes from low to high and from a continuous tone to a two beat sound. 4. Continue fine tuning until the buzzer is a two-beat sound. 5. After the beams are aligned, set DIP Switch 6 to OFF. 6. Repeat the procedure for the other optical module pair.

The ALARM LED should activate. If not, the beam interrupt time is set too low or the alignment is not correct. Walk across the beam path in several locations between the detectors (Figure 24).Each time you cross the beam path, the ALARM LED should activate. If not, the beam interrupt time is set too low or the alignment is not correct.
